To allwlzom z't mag-concern:

Be it known that I, DAVID STRAND, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Feed-Roll Gearing for Interlaoing Machines, of which the following is a specification.

This invention relates to improvements in machines for interlacing curled horsehair, and has for one of its objects, to provide an improved machine of this character, whereby continuous sheets of fabric may be rapidly and quickly manufactured.

A further object is to provide an improved machine of this character, having means whereby sheets of fabric of varying thicknesses may be produced. Y

A further object is to provide an improved machine of this character which will be simple, durable, cheap, compact and comparatively lightin construction and effective and eflicient in operation.

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts, hereinafter more fully described and claimed and shown in the accompanying drawings illustrating the invention and in which;

Figure 1 is a. view taken on line 11, Figure 2 of an improved machine of this character, constructed in accordance with the principles of this invention.

Figure 2 is a vertical sectional view taken on line 2 2, Figure 1.

Figure 3 is a, view taken on line 33, Figure 1.

Figure 4 is a detailview of one of the bearings for the rear roller. 7

Figure 5 is an enlarged detail view partly in elevation and partly in section of one form of needle and needle holder.

Figure 6 is a diagrammatic view showing the relative position ofone of the needles with respect to the disk rolls.

Figure 7 is a view showing a portion of fabric and the operation of the needles with respect thereto.

Figure 8 is a detail view of a portion of another. form of needle.

Referring more particularly to the drawings, the numeral 10 designates generally a supporting frame or structure having a power shaft 11 journaled thereupon and which shaft receives its motion from any suitable source of power, A reciprocating head 12 is mounted upon the frame and in which head are secured the needles 13, any number of which needles may be provided according to the width of the fabric desired to be produced.

The reciprocating head is connected with the power shaft 11, in any suitable manner, such as by means of one or more eccentrics 11 on the shaft 11, and a strap 15 connected with the eccentric and the reciprocating head 12.

Journaled in suitable bearings, extending transversely of the frame, and preferably beneath the reciprocating head 12 is a roller, preferably comprised of a series of disks 16, and which disks are spaced laterally from each other and secured to a suitable Shaft 17. A

A similar roller comprising spaced disks 18 is arranged above the disks 1G to cooperate therewith, and these rollers are so arranged with respect to the needles 1.3, that the shaft. 17 of the disks 16 will be substantially directly under the needles 13, and the shaft 19 to which the disks 18 are connected, is preferably displaced laterally with respect to the shaft 17, so that the needles during their reciprocation willpass between the disks 18, 16. The shaft 19 and the disks 18 secured thereto are preferably journaled in a fixed bearing, while the shaft 17 and the disks 16 connected therewith are preferably mounted in shiftablebearings 20. The shaft 19 is the operating shaft for the rollers and receives its motion preferably from the reciprocating head 12 through the medium of a pawl 21, which engages a ratchet wheel 22 secured to one end of the shaft 19. The pawl is connected by a means of a suitable link 23 with an arm 24,

which latter is in turn connected with the reciprocating head 12, so that as the head 12 is reciprocated, an intermittent rotary motion will be given to the disks 18.

Connected with the other end of the shaft 19, of the upper roll, is a gear 25, which It will thus be seen that when the head 12- is reciprocated and'the upper disk roller to which is secured the gear 25, is rotated, motion will be imparted tothe lower roller,

7 and through the medium of the idlers, both the upper and lower rollers, or rather disk rollers will be given a rotary motion in the same direction.

In order to maintain the gears connect ng these rollers always at the same relative distance during the adjustment of the rollers towards and away from each other, to vary the thickness of the sheet of fabric, links 29, 30 are provided, which are of a uniform length and are pivotally connected by one extremity as at 31, and the connecting pivot 31. forms the bearing or journal for the gear 27. The gear 26 is journaled as at 32 at the free end of the link 29, and the free end of the link 30 is pivotally connected with the shaft 17 of the lower roller, so that thegears 26, 27 will be supported by the links 'and will be in the nature of floating gears. It. will thus be seen'that when the bearings 20 which latter are supported by means of suitable pivots 33, are shifted about their pivots in manner to be hereinafter setforth, to vary the distance between the rolls, the links 29, 30, will maintain the connecting gears always at-the same relative distance.

The bearings 20 arranged on opposite ends of the machine, are connected for simultaneous movement about their pivots by means of the shaft 17 and they may be shifted about their pivots in any desired or suitable manner, preferably by means of cams in the form of eccentrics 34, one oneach end of the machine,ha ving contact with the respective bearing 20. These cams or eccentrics are connected preferably by means of a bar or shaft 35, extending acrossthe machine, and an operating handle 36 may be connected with the shaft 35, so that both eccentrics may, be actuated simultaneously and from one end of the machine. Thus it will be seen as the earns 34 are rotated, and as they contact with the bearings 20. the hearings will be raised, thereby raising the lower disk roll, and when it is desired to separate the rollers, the cams are moved so as to permit the bEfLIlIlQS to drop by their own weight.

Arranged m the rear and spaced from the upper disk roll is another roll 37, which is preferably continuous, and a co-operating roller 38 is arranged in rear of and spaced from the lower disk roll. These rolls are adapted to receive the finished fabric from the disk roll and convey the same from the machine. The upper roll 37 receives its motion by means of a gear 39 connected with the roll, and an idle gear 40 meshes with the gear 39 and also with the gear 25 on the upper disk roll, and which gear 25 is of a suitable width so as to mesh with the gear 40 and also with the gear 26.

Connected with the lower roll 38 and preferably on the opposite end of the ma chine is a gear 41 which'meshes with an idle gear 42 that is journaled as at 43 in the adjacent bearing 20, and this gear "42 meshes with another gear 44 which is secured to the shaft 17 of the lower disk roll. Thus it'will be seen that the upper rear roll 37 will receive its motion from the "upper disk fell from one end of the machine, while the lower roll 38 will'receive its motion from the lower disk roll from the other end of the machine.

The material to be interlaced is fed from a suitable support 45 between the disk rolls. and these rolls impart an intermittent movement to the material. During the interval of rest of the passage. of the-material through the machine, the needle will penetrate the material and partially remove a portlon of the material from the supply, after which the needle will be withdrawn the needle will again penetrate the material.

The thickness of the sheetof fabric is controlled by adjusting the distance between the disk rolls, and after the material passes out of engagement with the disk rolls, it is caught by the rolls 37, 38 and" delivered from,

the machine. V In Figure 8 is shown another style of needle and with this needle, the material will be partially drawn from the supply, while with the form of needle shown in Figures 5 and 6, the material will be partially forced from the supply. 7 r

In order to vary the distance between the rolls 37, 38, the roll 38 is mounted in ad justable'bearings '47 which are secured to the supporting structure. These'be'arings 47 are preferably provided with a slot 48' through which the fastening devicepasses. When it is desired to adjust the roll 38 with respect'tothe roll 37 all that" is necessary is to loosen the fastening and adjust the bearing 47 to any desired extent.

After the bearings 20 have been adjusted by the eccentrics 34,"and in order to maintain the parts in their adjusted positions,

the shaft 35 may be provided on its extremities with nuts 35 which latter are adapted to be adjusted to release the eccentrics, and after the eccentrics have been adjusted to move the bearings into the proper positions to maintain the desired space between the disk rolls, the nuts may then be tightened and the eccentrics will be clamped against movement. 7
